HAIR-DRYING DEVICE.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed September 25, 1915. Serial No. 52,676.

"o all ywho/m, t 'may concern.'

Be it known that I, GEORGE L. SCHEEL, a citizen of the United States,and a resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in Hair-Drying Devices, of which the following is a specification.

My invention relates to improvements in hair drying devices and has forits object the production of a device of this character which will be ofimproved construction and efficient in operation.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanying'drawings, forming a part of this specification, and in which,

Figure 1 is a side elevation of a hair drying device embodying theinvention, Fig. Q is a top plan view thereof, Fig. 3 is a centralvertical longitudinal section of the device, F igs. 11 and 5 areenlarged sections taken on lines azz-m and aj-Jy respectively of Fig. 3,and Fig. 6 is a detail plan view of one of the insulating membersemployed in the construction.

The preferred form of construction as illustrated in the drawingscomprises a comb 1 from the back of which project spaced teeth 2. Formedin said comb back is a longitudinallyT extending cylindrical chamber 3and a longitudinally extending air passage -it which preferably tapersor converges toward its forward end. Leading from the passage Ait to theteeth 2 are branch passages 5 which converge or taper toward their outerends. The branch passages 5 are lormed as described in order to securethe greatest pressure upon the air discharged at the point of itsemission, it being clear that with this formation of the branch passagesconcentration toward the outer ends of said branch passages is effectedwith the result that a greater pressure upon the air will be secured atthe outer ends of said passages.

Cooperating with the comb is a handle 6 the front end 7 of whichtelescopes with the rearward end of the back of the comb as clearlyshown in Fig. 3. Said parts are held in operative relation by means ofscrews S. Formed in the portion 7 in axial alinement with chamber 3 andpassage i are openings 9 and 10 respectively.

Arranged at the under side of the handle G 1s a compressible rubber bulb11 one end of which engages with'a cap 12 secured by screws 12 to therearward end of handle G, an inwardly projecting nipple 13 secured tosaid cap engaging the opening provided in the adjacent end of said bulb.The opposite end of said bulb is held in operative position by means ofa tube 14 which connects opening 10 with the passage 4 as shown, therearward end of said tube projecting beyond the adjacent side of portion7 for engagement in the opening in the front side of bulb 11. With thisarrangement it will be seen that bulb 11 is detachably secured inposition, detachment of the same being readily and easily effected bydisengaging the respective ends thereof from nipple 13 and tube'lt.Cooperating with the nipple 13 isa check valve 15 of the flap valve typeand provided in the forward end of tube 111 is a check valve 16 in theform of a disk adapted for slight movement in moving' toward and fromclosing position. The tube 14' as will be seen is corrugated, and thecorrugation provided in the forward end of said tube serves as a seatfor the valve 16 in the checking operation of the latter. The eXtremeforward end of tube 14C is longitudinally corrugated in order to allowfor escape of the air around the valve 16 when the bulb 11 iscompressed. With this arrangement it will be seen that throughsuccessive compressions of the bulb 11' air will be pumped thereby intothe passage 4C for discharge through the branch passages 5 as will bereadily understood.

Arranged in the tube 14- is a perfuming element 17 in the form of apiece of porous fibrous material which is saturated with any desiredperfume. The member 17 is carried at the forward end of a resilient stem18, the rearward end of the latter being bent back upon itself andformed for engagement with the corrugations at the adjacent end of tube11 in order to releasably hold said perfuming device in positiontherein. lith this arrangement it will be seen that air discharged fromthe bulb 11 will be perfumed in its passage through the tube 14. Theperfuming element is located in the discharge end of bulb 11 rather thanat the entrance end thereof for the reason that in the latter case ithas been found that considerable ot the pertume is wasted and spentbefore the same is discharged from the comb. lilith the arrangementdisclosed it will be seen that the air is discharged practicallyimmediately a'tter being periumed, thus` preventing wasting of theperfume.

arranged in the chamber 3 is a heating element in the 'lorm ot a wire1t) ot high electrical resistance which is wrapped upon a. tubular core2O of insulating material and prelrably mica. interposed between thewire li) and the walls ol chamber is a second tube l of insulatingmaterial also pre-- erably ot' mica. One of the terminals ot the heatingcoil 1) is connected with one pole ot a switch 2*) which is mounted inarecess 23 formed in the upper side of handle G adjacent the front endthereof, a cover plate 2i secured to said handle by screws serving tosecurely hold said switch in position. rl"he other terminal ot saidheating' coil is connected through the medium of a screw 25 with onewire 2G of a pair ot leed wires which lead to the device, the other leedwire 2T being connected with the other pole o'l the switch 22 as clearlyshown iirl'iig. With this arrangement it will be seen that the switch 22controls the cir cuit ol' the heating element 1S), making and breakingof said circuit being ettected through depression ot laterallyprojecting linger pieces 2'! which project exteriorly through theopposite sides ot the inclosing member Q-l. rI`he feed wires 26 and 2TeX- tend along the inner side of handle t3 which is grooved as at 2S inorder to accommodate said wires. A sheet 29 of insulating material isinterposed between said feed wires and the bulb 1l for the protection ofthe latter. 'fthe forward end of the member 91 is o'l`V channel form asshown at 30 in Figs. S and o in order to accommodate the adjacentterminal olE heating coil 19, the opposite end ot said insulating`element being formed with a lip 31 which embraces an adjacent edge ofhandle G to securely hold said insulating member in operative position.A flexible housing 32 surrounds the 'Feed wires QG and 2i at their pointof entrance to the handle (l to prevent too sharp bending ot the same aswill be readily understood. Ii'ith the construction set forth it will beseen that when heating coil 19 is energized through closing of thecircuit therethrough, the back portion ot the comb will become heatedwith the result of heating the air passing through the passage l andwhich is discharged through the branch passages 5. 'l`he eliectivenessot the device as a hair drier is thus obviously increased.

In other hair drying devices which I have constructed as tor example inthe hair drier shown in my Patent #1,137,792, dated May 4th, 1915, Ihave mounted the control switch tor the heating element of the device inthe comb portion thereof. However I tound through experiment that theheat generated by the heating element when in use was communicated tothe switch, to the injury of the latter. In the present constructionhowever it will be seen that I have corrected thisI defeet inconstruction through mounting otl thc switch well within the handle olfthe device and therelore out ot the zone ol the hating element 19. Thedevice is olf durable and economical construction, ot neat and tinisheddesign, and may be readily and easily manipulated by anyone.

AWhile I have illustrated and described the prelierred ilform otconstruction tor carrying my invention into ell'ect, this is capable otvariation and modilication without departing from the spirt ot theinvention. I, therefore, do not wish to be limited to the precisedetails ot construction set Vtoi-th, but desire to avail myself of suchvariations and modiiications as come within the scope ot the appendedclaims.
